This preamp is based on the Marshall Lead 100 MOSFET, a mid-gain amplifier known for sharing much of the tonal character of classic Plexi and JCM800 tube amps. Its MOSFET design delivers a punchy, responsive feel, while still offering the familiar Marshall grit and growl.
With two channels, a dedicated “Tone” control on the lead channel, and the option to partially bypass the tonestack for a mid-forward crunch, it provides a surprisingly wide range of sounds. The result is a versatile amp circuit capable of everything from classic rock bite to fuller, thicker overdriven tones.
